Indeed there is recourse beyond walking. Social enforcement has a lot more tools up it's sleve than that. First I would do is merely pointing out that I found the situation unpleasant. If you have a halfway decent DM that alone should be enough to trigger some emotional response in them that is likely to make them correct course.
See "bad players".
Okay, that was overly terse. But watch how often a player that doesn't immediately fold when in a disagreement with a GM gets written off in discussion as the problem. There's never even the faintest hint that they might be in the right and the GM just doesn't want to engage with it for any number of reasons, some maybe valid, but some not nearly as clearly so.
